Kratom (pronounced kruh-TAHM) is a lesser known herb that many use for pain relief and as a stimulant. Popular in Thailand and other SE Asian countries, it's est'd up to 70% of men use it in a manner similar to how some use energy drinks here in the U.S. Like cannabis it threatened the opioid market and is much safer than the prescription drugs it can often replace. Don't let the feds make it illegal in your state.
